ADOT replacing two bridge decks over I-10 southeast of Tucson

Overnight lane closures scheduled in each direction of I-10 near SR 83

August 19, 2019

PHOENIX – Drivers who use Interstate 10 in the Vail area during nighttime and early morning hours should budget extra travel time for approximately two weeks starting Wednesday, Aug. 21. Lane restrictions are needed for an Arizona Department of Transportation project to replace two bridge decks spanning the freeway southeast of Tucson.

Bridges at the State Route 83 and Colossal Cave/Wentworth Road interchanges will be upgraded during this project, which is scheduled for completion in fall 2020. Crews will begin with the SR 83 bridge and then move to Colossal Cave/Wentworth Road.

I-10 will be reduced to one lane in each direction overnight near State Route 83 from 8 p.m. to 6 a.m. starting Wednesday evening. A 45 mph speed limit will be in place in the work zone. The restrictions will allow crews to construct a temporary bypass in the interstate median.

Starting in early September, the SR 83 bridge over I-10 is scheduled to be reduced to a single lane with traffic controlled by a signal. In addition, overnight bridge closures will be required at certain points during this project.

Real-time highway conditions and restrictions for improvement projects are available on ADOT’s Arizona Traveler Information site at az511.gov, by calling 511 and through ADOT’s Twitter feed, @ArizonaDOT. When a freeway closure or other major traffic event occurs, our free app available at ADOTAlerts.com will send critical information directly to app users in affected areas – where possible, in advance of alternate routes.
